| Summary: | The effect of an oscillatory motion of a viscoelastic fluid over
an infinite stretching sheet through porous media in the presence
of magnetic field with applied suction has been studied. The
surface absorbs the fluid in a porous medium in the presence of
magnetic field and the velocity oscillates depending on the
stretching rate (b). Analytical expressions for the velocity and
the coefficient of skin friction have been studied, first by the
perturbation method and then by power series method. The effect of
viscoelastic parameter k1, porous parameter k2, magnetic parameter Mn, and the vertical distance x in the presence of
suction/blowing on the velocity and the flow characteristics are
discussed. The velocity of the viscoelastic fluid is found to
decrease in the presence of magnetic field and porous media, as
compared to the study of viscous fluid. It is also found that the
effect of unsteadiness in the wall velocity and skin friction are
found to be appreciable in the presence of suction/blowing
parameter. |
